Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a bag breaking device for cutting bags such as vinyl bags containing dust.

[0002]

2. Description of the Related Art Conventionally, there has been a bag breaking apparatus for cutting bags with a blade while carrying bags containing dusts or the like with a conveyor belt. However, as shown in the schematic side sectional view of FIG. 5, the conventional bag-breaking apparatus includes a sprocket 103 and a sprocket 104, each of which includes a plurality of pans 101, 101,. Are moved in the direction of arrow A to fix the bags 106, 106,... Containing the dust put in the hopper 105 to the frame 107 above the transport pan belt 101 while moving in the direction of arrow A. Are provided to cut the bag containing dust, and a baffle plate is used to adjust the amount of the bag containing dust conveyed to the conveyor pan belt 102. 109 was attached. 110 are side plates for preventing bags containing dust from spilling from the side of the cutting pan belt 102, and 111, 111... Are joints of the pans 101, 101. Are provided on the roller.

However, in the conventional structure, the bag containing dust is caught by the baffle plate 109 and becomes clogged, and the bag containing dust is cut on the transport pan belt 102 by a cutting blade. In many cases, the device was caught and clogged, and it was necessary to stop the device and adjust the amount of bags containing dust each time.

[0004] Therefore, it is necessary to improve the structure of the bag breaking device so that the bag containing the garbage does not get caught or clogged in the bag breaking device.

[0005]

[Means for Solving the Problems]

 The present invention solves the above-mentioned problem, and is designed to prevent a bag containing garbage conveyed on a conveying pan belt from being caught or clogged. A sprocket is attached to both ends of a transport pan belt, which is formed by connecting both sides of a pan with a chain, and is rotatably mounted. The dirt is attached diagonally upward from below, and dust is placed on the lower side of the transport pan belt. A hopper for putting bags containing the hoppers is attached, while a small gap is opened on the transport pan belt, and a large number of buns are provided with cutting blades with cutting edges directed in the rotation direction described later. A sprocket is attached to both ends of a cutting pan belt that is connected to both sides with a chain, and it is rotatable by attaching sprockets.The upper surface of the transport pan belt is obliquely upward from below. And the lower surface of the cutting pan belt is rotated in the same direction as the upper surface of the transport pan belt and at a higher speed than the upper surface of the transport pan belt. The bag containing the garbage is cut by the cutting blade implanted in the cutting pan belt while being conveyed on the upper surface of the conveying pan belt, and the cutting pan belt in the bag breaking device. The end on the hopper side protrudes inside the hopper.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail based on examples shown in the drawings. FIG. 1 is a schematic side sectional view of a speed differential type bag breaking apparatus for carrying out the present invention, FIG. 2 is a top view of the transport pan belt of the present invention, and FIG. 4 is a side view of the transport pan belt. However, as shown in the above figures, both sides of a large number of pans 2, 2,... On which the conveying claws 1, 1,... Are planted are connected by a chain composed of rollers 3, 3,. Thus, the transport pan belt 5 is configured.

The transport pan belt 5 is configured so that both ends thereof are stretched over a sprocket 6 and a sprocket 7, and the sprocket 6 and the sprocket 7 are configured to rotate in the direction of arrow A in the drawing. In addition, as shown in the detailed top view of FIG. 2 and the detailed side view of FIG. 4, the transport pan belt 5 has garbage-containing bags spilling from both sides of the pans 2, 2,. Are provided in order to prevent the above.

The transport pan belt 5 configured as described above is rotated by the motor (not shown) to rotate the sprocket 6, that is, the lower surface of the transport pan belt 5 in the direction of arrow A in FIG. However, it is configured to be swung obliquely upward from below.

As shown in FIG. 1, a hopper 9 for loading bags 10 and 10 containing dust is mounted on the lower side of the transport pan belt 5. On the other hand, as shown in FIG. 1, a cutting pan belt 11 is disposed substantially horizontally above the conveying pan belt 5 at a slight interval from the conveying pan belt 5, as shown in FIG. .

The structure of the cutting pan belt 11 is similar to the structure of the transport pan belt 5, as shown in a schematic side sectional view in FIG. 1 and a detailed bottom view in FIG. On the upper side, cutting blades 12, 12,... Sharpened in the direction of arrow B in FIG. 1 are planted, and these pans 2, 2,. And a chain comprising ring plates 4, 4 shown in FIG. 3 to form a cutting pan belt 11. As shown in FIG. 1, both ends of the cutting pan belt 11 are sprockets 13 and sprockets. 14 and is installed substantially horizontally.

The lower surface of the cutting pan belt 11 is rotated by the sprocket 13 in the same direction as the upper surface of the conveying pan belt 5, that is, in the direction of arrow B in FIG. The cutting pan belt 11 has an end on the hopper 9 side protruding into the hopper 9 as shown in FIG.

Next, the operation of the speed difference type bag breaking device of the present invention will be described. As shown in FIG. 1, the bags 10, 10,... Containing the trash put into the hopper 9 are put on the transport pan belt 5 and rotate rightward in the figure. At this time, the transport claws 1, 1,... Serve to transport the bag 10 containing the dust by hooking the bag 10 containing the dust and transporting the bag 10 in the above-described direction.

Since the lower surface of the cutting pan belt 11 also rotates in the same direction as the upper surface of the transport pan belt 5, the bag 10 containing the dust is transported in both directions by the two. However, as described above, the lower surface of the cutting pan belt 11 rotates faster than the upper surface of the transport pan belt 5, so that the bag 10 containing dust is cut during the transport. Are cut by the blades 12, 12,....

[0014]

【Example】

 In the embodiment, the cutting pan belt 11 is configured to rotate at a speed five times as high as the speed of the transport pan belt 5, thereby effectively removing the dust. The bag containing it seems to be cut.

In addition, air cylinders (not shown) are attached to the essential parts of the transport pan belt 5 and the essential parts of the cutting pan belt 11, and bags containing large dust are thrown in. In such a case, the interval between the transport pan belt 5 and the cutting pan belt 11 is increased, and the air cylinder is configured to return to the original position.

[0016]

[Effect of the invention]

 In the present invention, first, the lower surface of the cutting pan belt 11 is rotated in the same direction as the upper surface of the transport pan belt, that is, rightward in FIG. Since the blade is not fixed, there is little possibility that the bag containing the dust is clogged. In addition, since the lower surface of the cutting pan belt 11 rotates faster than the upper surface of the transport pan belt 5, it is effective. The garbage bag will be cut.

Further, as described above, the end of the cutting pan belt 11 is configured to protrude into the hopper 9, so that the bag 10 containing dust is moved from the hopper 9 to the transport pan belt 5. In addition, the risk of clogging at the entrance is reduced.
